In this blog post, we’ll explore a way to write unit tests for a Django model using Model Mommy. Our main focus is on the update_dog_from_data function, which updates a Dog object with JSON data. However, the highlight is the technique to dynamically access attribute values in the tested object. By the end, you’ll learn some unit testing strategies and gain insights into dynamically interacting with object attributes during testing.

Yes! Indentation, or leading white space at the beginning of a line is required in Python. You can read more about why that is important here. And here is the part of the style guide convention for indentation (PEP 8).

Python has three similar data structures that can hold an unordered collection of elements: list, tuple and set.

My primary debugging tool is to add print statements to my programs</confession_time>. Print statements are very easy to use and they work well for any simple scripts. But that’s the catch: if you’re debugging an application and/or a test file, print statements won’t be enough or will just not work (in the case if tests files).

OR: Run a Python script with arguments

You can add arguments to the command line when running python scripts by importing the sys module from Python’s standard library and using its argv function.
